To-al'l whom it mar concern: i Be it known that I, FREDERICK S. Wim- NEY, a subject of the King-off Englanime siding at New York, in the county of New York and {State of New York, *have invented new and useful Improvements in. Amen ments vfor Cable-Recorders, of which vthe following is 'a'specification. i I e v This I invention re'l t es to attachments for submarine cable recorders, and theobject is ;to provide certain rnovel means "under the control of the usual rotatable coil whereby the solenoids of "the tape punching devices are more effectively controlled than by ap' paratus now 'in use." 7 j j A further object is 'tolprovide' for'fthe "control of a pluralityof relays andci-rcuits, certain of which indlude a vibrator, by means of contact making elements 'conrprisinga disk 'member'or pan rotatable on a vertical axis mountedin jewels and carry: ing 13111901 tongues cooperating with stationary tcontact elements for, completing a circuit and actuating imeans for punching a continuous .row of aperturesin the'middle completing a circuit energizing means for indicating at the required time the dots of the Continental ,or International code, and certain of sardpms or prongs complet1nga circuit energizing means for indicating dashes, the various operations specified'b'eing independen'toi each other.

w t the foregoing and other objects in "view, the "invention consists in the novel construction, 'comblnat on and arrangementv of elements hereinafter described and claimed. V j v In the accompanying drawings'z-e Figure 1,,is atop plan view showing the rotating coil connected with the rotatable disk or panand showing the associated con tact making elements.

"(Fi s 3, 4 and T e structure shown at the '1e"ft :of 1

and the structure shown in Figs. 3 and 4 is more or less conventional and of the general type now inuse, the poleextensions of the *magnet being designated 16) and 12, and

the rotating coil between these poles being designated 16. This coil has connection by means of fibers of silk or the like 15 with a rotatably mounted pan or disk of aluminum designated 17 and mounted on a staff 18 whichin turn i-s-inourited in jewels to per-.

ruit of the free movement of the staff and the pan "mounted "thereon, and adding greatly to the-sensitiveness off the instrument.

carrying silver pointed contact screws2'7,

28' proje'cting *towardeach other and en-* gaged by brass contact member s' i29 and 30 carried by disk 17 at one-si'detheredf.

I A' pluralityof bindingposts32and 33 are also threaded transversely and accommodate-adjusting screws 84, 35 each contacting with -apivotally mounted arm formed of. fbrass, these arms being designated 38, 39

andbeing under thecontrol of fine springs or hair springs 40. The pivotal mounting of these arms :38, 39 is at the point shown,

and'they approach each-other-at a point adjacent to the iirontside of the disk, as distinguished from the side'or edge where contact -members 29 and 30 are located; A pin or projecting member 42 of silver is located at the edge "dfthe disl :andbet\veen the pro jecting ends of arms '38 an'd39.

'It will be understood 'that the movement of the coil ldcauses acorrespondinginoveymen'tof the-disk "17 in onedirection or the other.

I The vibrator of a given type may be of substantially the form now in use exce t that I-employ a deviceelectro magnetical y controlled but otherwise similar to that shown "in llnited' States Patent #ipaaaae.

The projection "or tongue 4Q=carried by the -pan is of "silver and the swing of -the recorder coil to eitherside causes the silver tongue to open the arms 38 and 39, breaking contact on contact screws 34, 35, and opening contact on the vibrator.-

A particular feature oftheinvention is the return of disk 17 to normal position under the influence of spring-held arms 38 and 39, either arm acting as the positive agent (depending upon the .direction of movement), and the other as a cushioning'de-" vice, thereby reducing jarring and' false vibration of the elements, including coil 16,

to a minimum. Elements 38 and 39 have therefore an important mechanical function, closely related to the electrical opera tion described below.

When the arms 38 and 39:"are closed, they 7 make contact on screws 34 and 35,'closing contact on the vibrator. specified, which in.

vibrating opens and closes by suitable means the circuit for .thecentral solenoid designated. 60, the core of this solenoid operating pivoted lever 61 controlling a suitable per.- forating device as in the well known type of such instrument. The other solenoid coils are designated 62 and 63 and control respectively, through the cores thereof, pivoted levers 64 and 65, these each being mounted with lever 61 on a transverse shaft or the like designated 66 having itsbearings in vertical posts or pillars '67 and 68. Each lever 61, 64 and 65 is designed to operate a perforating member for punching holes in a tape in the well known manner. I

It should .be stated that the vibrator opcrates only when the arms 38 and 39 are in contact with-tongue 42 carried by-the disk 17, the'elements then being in the position shown in, Figs. 1 and 5;

The brass contact tongues 29 and 30 car-.

ried by the, rear po rtion of the disk 17 make contact on screws 27 and 28 when the coil 16 ofthe recorder is moved to eitherside continuously, completing indirectly. the circuit for coins 62 and 63 of the perforating device; 1 V

The variation of the position of coil lay-reason of the impulses receivedover the line wires causes the corresponding movement of disk or pan 17.- Upon the completion of a local battery circuit and; assuming that disk 17 isfin its normal position, the coil (SO-will be energizedfor punching a continuous row of apertures centrally of the tape. W hen'the disk swings in either direction, coil'62 or 63 will be energized, as the case maybe, and coil willbe deenergized so that only one of the levers 61, 64, 65

will operate at a given instant Coils 62 and63 punch apertures on opposite sides of the central row of apertures in the tape, and one of them is operated for the dashes and the other for the dots. The circuitsfor the-coils last named areclosed by relays controlled by local circuits through a'local battery, andthrough the Various contacts coaaona directly by disk 17. This 150a battery'is designated 71 and the source of currentfor the "110-volt circuits for thesolenoids is shown conventionally at 72.

The central rowof holes is punched in the tape as a result of the operation of solenoid 60, the circuit being from local battery 71 through Wire 78, wire 74, relay 60, wire 76, vibrator 77, wire 78," binding post 84, wire 79, binding post 33, screw, 35, arm 39, pin

The circuit from-72 is throu h wirelOO wire 1 01,00 11 60, wire 102, contact 94' of armature 94, through that armature thence through wireflOS, contact 93 armature .93 wire 104, to contact 91, armature '91, wire 105, 'wire 1.06, resistance 107,'to source 72. The purpose of solenoid 60 is to provide spaces or central "holes betweenclette'rs' and words, providing for one space after each letter and threespaces after each word, as in-the strip manually punched at the transmitting end. This arrangement is carried out in order to insurereliability in trans- Each time the circuit is completed. through mission. hen disk 17fis'in normal position and the circuit through pin 42 closed, central holes are continuously punched in the strip. 1 QW hen the disk is'moved to either side,

Assuming that the disk '17 swings in a given direction by reason of a corresponding movement of coil 16, contact is made be tween screw 28 and contact pin 30. .A circuit is thencompleted through local battery 71,

Relay 62 is energized by a circuit through contact '29 and screw 27 when the disk 17 swings in a direction opposite to that previously mentioned.

The circuit through contact 29 is through disk 17, wire 86, binding post 83, wire 87, battery 71, wire 7 3, Wire 74, the coil of relay 62 wire 125, the coil or relay 113, wire 126, binding post 81, wire 127, binding post 25, screw 27 to contact 29.

At this timethe circuit through contact 94 is broken, deenergizing solenoid 60, and contact is made at 95 completing a circuit through solenoid 63, including source 72,

Provision has therefore been made for energizing solenoid for punching the central row of. apertures in the tape, when the disk is in its normal position as shown'at Fig. 5. Provision has also been made for energizing solenoid 62 of the dot punching device, when the disk is swung to one side,

to stem 18, a portion of the current may pass through element 38, screw'34c, and wire 87, binding post 85, wire 85', and wire 87, to 71.
